Thanks!
fortunately, I'm not having any difficulties (gaming or otherwise). I only do moderate O/C'ing. Backside temp stays at 50C or so under max load. It's well below what I would see with a stock HSF and no OC. I just wanted to reduce stress for extention of useable lifetime of the CPU and RAM.
On the upside, I usually upgrade long before I've had time to wear much of anything out.
I like the entire DC idea (well, maybe not the search for ET thingy) and will probably let it stay for a bit.
